<br><font size=2 face="sans-serif">S Accessom nepracujem, ale ak to co
chces ide vseobecne cez ADO, tak sa to da odkukat z nejakych prikladov
napr. vo Visual Basicu a malo by to fungovat aj v Pythone podobnym sposobom.

<br><font size=3>Ahoj, <br>
<br>
potřeboval bych nějak z python skriptu stvořit access databázi (mdb
soubor) a aby toho nebylo dost potřeboval bych v ní ještě vytvořit
relace. Je soubor datové výměny která probíhá denně. Ty relace stačí
vyrobit až po vytvořeníé tabulek.<br>
Přítomnost accessu neni problem. <br>
</font>
<br><font size=3>Díky za všechny typy.</font><tt><font size=2>_______________________________________________</font></tt>
